Granted: 1996-10-01
Abstract: There is provided an apparatus for reducing pair to pair cross talk which arises in electrical connectors (10, 11) due to closely spaced elongated parallel conductors (16, 18, 22, 24).  The cross talk which occurs within the connector (10, 11) is reduced by modifying certain circuit paths either inside or outside of the connector (10, 11) so that each conductor of a first pair (T1, R1) which is parallel to and cross talking with an adjacent conductor of a second pair (T2, R2) in the connector (10, 11) is  relo-cated adjacent and parallel to the other conductor of the second pair (T2, R2) over a predetermined distance.  It is preferred that the relocation of the circuit paths occur on a circuit board (32) which is attached to the connector (10, 11).

Title: Process for biolixiviating copper sulfides by indirect contact with separation of effects
Inventor: ARAGONES JUAN LUIS BOUSO
IPC: C22B15/00
Filed: 1994-01-07
Granted: 1999-04-06
Abstract: Process for biolixiviating minerals from copper sulfides and also from their flotation concentrates, characterized by the use of biolixiviation through indirect contact as well as separation and improvement of the chemical and biological steps of the biolixiviation process.  In the chemical step, a low concentration of ferric sulfate is used as the lixiviating agent.  In the biological step, bacterial films of Thiobacillus ferrooxidans attached to an inert solid are used to regenerate the lixiviating agent by converting the ferrous ion into ferric ion through oxidation.  The regenerated agent is then recycled to the lixiviation reactor.  The biolixiviation process permits complete extraction of the copper contained in the ore and results in a lixiviation liquor which contains all the copper charge and a low concentration of ferric sulfate similar to the low concentration of ferric sulfate used initially.  The copper obtained can be treated without difficulty by means of extraction with solvents and electrolysis in order to obtain cathode copper.

Granted: 2003-03-18
Abstract: A preferred embodiment of this invention is illustrated in Fig. 4 showing an offset and tilted object transducer (50) being rotated about a system axis (51) to sequentially insonify the object from various acute incident angles .THETA. to the system axis to pro-vide images of the out-of focus structures at spaced locations at the hologram detection surface (18) at different spaced times. If the pulse rate of the object transducer is greater than the fusion of the eye, the eye is able to average two or more images into a single perceived image. Likewise, video equipment that receives images at a rate greater than 30 Hertz will average two or more images and display the image at a rate of approximately 30 Hertz.  Additionally, external video processing may be utilized to elec-tronically average two or more images electronically to obtain an averaged image at any time constant desired by the operator. Such a system effectively neutralizes or blends the out-of-focus structure of an object spaced from a selected focus plane (27) while maintaining the structure within the plane in sharp consistent contrast to provide consistent, quality images of the internal structure of an object (12).

Granted: 1997-02-18
Abstract: The present invention relates to a roof drain structure comprised of a drain plate having an upstanding overflow port and a clamp ring used to secure an edge of the roofing substrate against the drain plate and around the overflow port.  The clamp ring surrounds and physically cooperates with the overflow port to align several screw apertures and the clamp ring with several corresponding screw apertures in the drain plate.  There are preferably at least two alternative drain plates having different size overflow ports, a larger one and a smaller one, and a clamp ring that may be modified to fit either of the different size overflow ports and still align the screw apertures. The preferred clamp ring has removable spokes that are left in place for use with a drain plate having a smaller overflow port and that are removed for use with a drain plate having a larger overflow port.  The overflow port is preferably stepped to have a lower larger portion and an upper smaller portion so that the contractor can modify the overflow port in the field to accommodate different sized drain pipes. The preferred drain structure also includes a drain grate and a plurality of alternative adapters that may be used to connect the drain grate to any one of several different sized pipes.  The preferred adapter includes exterior notches that allow passage of the removable spokes of the clamp ring.  In this fashion, it is possible to unscrew and remove the clamp ring without having to remove the ordinarily permanently cemented adapter.

Abstract: An energy-efficient, wood-skinned fire door having a laminate construction.  There is a core panel formed of a fire-resistant material, preferably mineral fiber board.  The perimeter frame around this has a channel formed in its inner edge for receiving the core panel in a close interfit therewith.  This supports the panel in the channel, and also eliminates any direct path for a fire to proceed past the edge of the fire-resistant panel.  Foil-covered thermal insulation panels are positioned on opposite sides of the core panel, and these are covered with wooden door skins.  This provides a structure which is highly fire resistant and exhibits excellent insulation qualities, yet which is also aesthetically pleasing so as to be suitable for residential use.
